Hello,

I've stepped on this mail in list:
http://lists.netfilter.org/pipermail/netfilter/2004-November/056947.html

But I still haven't found any solutions for these two problems:

the second method, sterilizing IP
header information and stripping unneeded TCP flags would successfully
undermine this scheme. For the last Method, counting hosts behind a
router.
Striping the fragmentation flag for syn packets, and setting the IP ID to
'0', (like Linux and Free BSD both do) would make it impossible to count
hosts behind a NAT router.

Any ideas how to do that on 2.6 and latest netfilter?
